$#

The output format for printed numbers. This variable is a half-hearted attempt to emulate awk's OFMT variable. There are times, however, when awk and Perl have differing notions of what counts as numeric. The initial value is "%.ng", where n is the value of the macro DBL_DIG from your system's float.h. This is different from awk's default OFMT setting of "%.6g", so you need to set $# explicitly to get awk's value. (Mnemonic: # is the number sign.)

Use of $# is deprecated.
